Can Mid-Rise Buildings be Family Friendly?

Mid-rise, 5-over-1 buildings have become the dominant form of infill development in Portland and in many cities in the US.  It’s a building type that offers urban-scaled housing on a much lower budget than a concrete high-rise.  Very few of these buildings, however, are amenable to families.  In Portland, most newly constructed units are Studios or 1 bed rooms in the 500 square foot range.  While that reflects an influx of young, post-college professionals, the actual residents of these buildings include more families than you might expect, and at some point many more of those professionals are going have children.  The supply of single-family houses in most of the city is essentially capped by the lack of developable lots, so if the city is going to retain the new residents that have fueled Portland's renaissance we should be thinking about how we can create infill housing that supports multiple stages of life.  Mid-rise construction affords density and urban amenities, but in order to make it an attractive proposition for families we may need to rethink the prototype. 


So what would a mid-rise building look like if we truly designed it with families in mind?  Developers, thus far, have not had a lot of interest in this question, but one place it has been considered is in subsidized housing.

An interesting case study comes from Michael Pyatok, who has been at the forefront of affordable housing in the Bay Area for a generation.  I studied under Mike in grad school and, between his socialist rants, learned a tremendous amount about housing design. I’ve never met anyone who has such a firm grasp of the minutia of kitchen layouts and the exact closet space desired by different cultural groups. His approach to design involves a level of community participation that most architects would cringe at.  Beyond soliciting the residents’ advice on massing and preferred unit layouts, he also invites them to pick the style and suggest design elements.  It leads to a more colloquial aesthetic than most architects would appreciate, but it also leads to buildings uniquely fitted to a community.  If you want to design a family oriented building then working directly with the families that will occupy it is a very precise kind of market research.  Over time Pyatok’s firm has developed a variation on the ubiquitous 5-over-1 building that has become a template for their family oriented housing.

Nihonmachi Terrace in the International District of Seattle is typical of Pyatok’s work.  Most units in this project are two-story maisonettes, not flats.  Bedrooms are accommodated in an efficient upper floor plan while the entry level is an open living space.  According to Pyatok this plan is popular because it is considered the equivalent of a house.  It also allows every unit to have a living space with two exposures, limiting the bowling alley feel of many modern apartments.  However, this unit type also has a second advantage: it allows for a gallery access building without the persistent privacy concerns associated with a motel 6.  Bedroom windows are up out of the view of passers by while the kitchen forms a connection to the gallery.  Wrapping the building around a courtyard gives the gallery a sense of dignity and purpose that you won't find in a motel.  Pyatok laments the lack of landscaping budget, but even in its somewhat spartan form the courtyard provides a place at the center of the building that can be programmed or used as recreational space.  Since every unit connects to the courtyard directly, parents feel free to let their children use it as a play space.   A community room also opens onto the courtyard, reinforcing its role as the central recreational amenity.

Other buildings in Payatok’s portfolio are variations on the single-loaded courtyard type.  The Divine Legacy in Phoenix is an elongated version with more intensively developed landscaping.  Here the courtyard provides sheltered play space in a climate that is often too hot for outdoor activities. Flats are mixed with maisonette units to provide housing for a variety of lifestyles.

The Fox Court Apartments in Oakland are another variation still.  This plan divides the block into two courts, which Pyatok insists is necessary to prevent large groups of children from assembling and causing chaos.  The form resembles many late nineteenth century blocks in Europe, which contain several courtyards shared among multiple buildings.  In the European prototype blocks are often assembled by combining several single stair buildings with independent entrances.  Since these blocks contain a series of stair cores rather than corridors they can achieve through units that look out onto both the street and the courtyard.  American building codes require elevators and duplicate stairs the single-loaded, thus gallery access buildings are the only economical way to create through units.  In many European cities, 19th century perimeter blocks are a staple of middle class family housing.  Paris, Vienna, Berlin, Barcelona and a host of other cities that grew in the early industrial era are rife with examples.  Almost without exception these blocks contain a much higher concentration of families than can be found in most American cities.

Pyatok's buildings are not the kind of high design that gets a lot of architects excited, but sexy modern design is skin deep.  It is fun to imagine what some of these buildings would look like with  lux finishes and beautifully constructed courtyards. (See my last post for more on that)  And the single-loaded courtyard building is certainly not the only building type capable of housing families in cities.  But this type is worth studying because from a construction point of view these buildings are a minor adjustment to an established formula.  They are still 6 stories tall with wood framing over a concrete deck.  From a development or finance point of view any new prototype requires a leap of faith.  Subsidized housing allows more flexibility to experiment with new prototypes that are not yet proven in the marketplace.  Developers, and more importantly their financial backers, want to build tomorrow what sold yesterday.  But those developers and bankers ought to be paying more attention to affordable housing if they want avoid the historic problem of doing market research by looking in the rear-view mirror.  After all, the future is not always like the recent past.  The millennial generation is heading towards prime child bearing years and a lot of them really hate the suburbs.  For cities its a housing challenge in the making and its not the kind of change we can adapt to overnight.  The development world and city planners need to start thinking about this issue now.  Some cities, notably Seattle and Toronto, have mandated a certain quota of family size units in new apartment buildings.  Its a good start, but ultimately creating housing en mass that works for a more diverse demographic requires both thoughtful city policy and prototypes with proven success in the market.

Vernacular Housing in Montreal ..The Three-Decker


Close up view of stairs, landings, and balconies, the vernacular language of
 the city.

Recently I went on a short trip to Montreal.  It is a beautiful city, and one of its charms is this type of vernacular housing.  It is a type of three-decker (stacked flats) that feels a lot like a row house.  My girlfriend and I decided to forego the hotel experience and try AirBNB. We got a room in one of these three-deckers in the Mile End neighborhood with a balcony overlooking the street.  Montreal is a low-rise city and even from the third floor we could see several miles to the church towers of the old town.  It was a wonderful experience.  I have never been on a trip where I spent a lot of time in the hotel room, but when your room is on a vibrant residential street and has a balcony with a view of the city, it changes the equation.  We enjoyed several bottles of wine and a few meals on the balcony watching life go by.  We watched the downtown fireworks on Candada Day, and watched commuters bike past over breakfast.

Mile End, along with many of the city’s inner neighborhoods, is made up almost entirely of three-deckers.  The neighborhood was developed extensively in the late nineteenth and early twentieth century as a very dense streetcar suburb.   Streets in this area of the city are strikingly regular with buildings built relentlessly to a setback line.  Cornice lines are set within a tolerance of a few feet and facades are flat. Rarely is a street lined with trees. There is a no-nonsense quality to this area of the city that is partly a product of the need to create affordable working-class housing and partly a reflection of the city’s French heritage.  Much like New Orleans, Montreal is more embracing of European style urbanity than its Anglo counterparts.  Having come to Montreal after spending several days in Toronto, this was especially apparent.  By comparison, Toronto’s classic row houses with their bay windows and elaborate gables seem a little silly, as if they are gyrating in place in an attempt to imitate a more suburban dwelling.

Staying in a three-decker gave me an inside look at how these buildings work.  In many respects these apartments are more like a house than what most Americans are used to. Units have an independent entrance, light on several sides of the building, a generous amount of porch space and a small yard shared by the three apartments.  The anatomy of this type consists of three stacked flats, in an L-shaped arrangement that allows light and air into every room.  Each unit has a small balcony in the front and a larger rear porch that is set in the crux of the L.  The most interesting aspect of this type is the system of vertical circulation.  The ground floor apartment is accessed directly from a small stoop while an external stair leads to the second floor apartment and a door to an internal stair that connects to the third floor unit.  Each apartment has private outdoor space in the front of the building and in the summer time these spaces are used extensively.  On the ground floor this comes in the form of a terrace that occupies the six to eight foot setback while the second and third floor have a shallow balcony opening off the living room.  This arrangement affords an independent, street-facing entrance to each unit, and generates a unique aesthetic of steel balconies, landings and stairs set against masonry facades.  On more prestigious streets these elements are an elaborate display of craftwork.

changed, but the type remains the same.

Montreal’s neighborhoods have continued to develop without fundamentally altering the three-decker type.  The modern examples I noticed have larger windows and presumably a more open floor plan, but in most other respects are no different from their predecessors. Probably the main reason this type has persisted is that it is cheap to build and uses expensive urban land effectively (nearly twice the density of equivalently sized row houses). Small buildings are often easier to accomplish where large streams of capital are not available.  A builder can put up a three-decker without incurring a lot of debt then sell it and repeat the process on the next lot. But as economical as these buildings are, they also add up to dense, attractive neighborhoods with a very unassuming scale.
